To (all whom it may concern:

Be it known that I, GIUsEPPn PIZZUTI, a

citizen of the UnitedStates, residing at Chicago,'in the'county of .Cookand State of Illinois, have invented a certain new and usefulImprovement in 'Wheel Removers, of which the following is aspecification.

vlwyinvention. relates to a wheel puller or remover, the purpose-ofWhich-is to enable wheels to be easily removed from the shafts on whichthey aremounted. My invention is applicableto any Wheel which must beremoved or pulledlofi ofa shaft, but I have illustrated it as applied tothe removal of automobile wheels, both of atype which ro-' tates onfixed axles and on floating removable axles.

Myinv'ention isillustrated more or less diagrammatically in theaccompanying drawings, wherein Figure 1 is an elevation of oneapplication of my invention;

Fig. 2 is an elevation of another method of using it; i H

Fig. 3 is a section'throughan automobile wheel the floating axle ofwhich has been removed, and

Fig. 4 is a section through an automobile wheel of the fixed type.

Like parts are represented by like letters and numbers throughout thedrawings.

A is an automobile wheel having a rim A spokes A and a hub A In Fig. 3 a

heavy truck wheel isv illustrated, with a heavy rim B, a solid tire Band hooks B such as are usually placed on truck wheels to secureanti-skid chains.

Adapted to engage the end of the axle C, as shown in Fig. 4, is thescrew-threaded shaft G which has at the outer end a perforated ball Cthrough whichpasses a bar or handle C which may be made removable ifdesired.

Mounted to travel on the screw-threaded shaft is the block or disk D,which is per-- forated as at D the perforation being screw-threaded tofit the shaft 0 in the disk D are four eye-bolts D to which are fastenedthe chains D the outer ends of which are fitted with the hooks D of asize proper to fit within the mesh of the chain. v

The inner end of the shaft 0 consists of a reduced cylindrical portion Ewhichterminates in a conical point E In Fig. 3 the invention-is seenapplied to drical portion E'of the shaft C The details of hub and axleare not fur-' ther described, since they. the present invention.

Secured an automobile wheel thefloatingaxle if i type, wherein the axlehas been removed. A bearingjdisk or block F is shown, which is adaptedto engage the edge F of the; axle housing. 7 rated as at F to receivethereduced form no part of This disk F is centrally perfo cylin- While Ihave illustrated Working are...

and one which has actually and successfully,

been putto' use, it will be realized that many changes might be made inthe shape, number, dispositionand relation offparts without departingfrom the spirit of my invention, and I do not wishto be limited to theform, or applicationherein disclosed. I

The use and operation of my invention are as follows:

Ordinarily when it is desired to remove an automobile wheel the hub capis unscrewed and the wheel is worked off by hand, v

at great exertion and with great delay.

lVheel removers, the details of which need not be herein given, aresupplied for some makes of car, but are not particularlyeflicient andare not adaptable to other makes and sizes. Applicant has'developed aWheel remover which not merely will fit all sizes and types ofautomobile and wheel but may be used to remove any wheel from any shaft.In the type of wheel which is mounted on a fixed axle, such asillustrated in Fig; 4,

the conical point E is applied to the end a of the shaft, the pointfitting'in-the lathe: center indentation which is always present at theend of the shaft. 'The chains are then hooked about the tire or securedto the hooks B of the rim, or looped about. blocks of wood as shown inFig. 4. -The hook is adjustable along the chain and the chains arenormally drawn'fairly tight to prevent any tendency of the block D torotate. The chains should be so adjusted that the shaft C lies along aprolongation of the axis of the axle. The operator then turns the handleC and the rotation of the shaft C causes the block D to travel toioowards theouter end of the shaft. Ayery few turns of the handle isvsufiicient to loosen" the wheel, particularly if the operatortaps theaxle or the wheel to aid' the loosening In the form of axle shown inFig. 3, where the floating axle is removed from the axle casing andthere is no axle end against which the shaft C can bear, the block ordisk F is used, the perforated center of which rotatably receives thereduced end E of the shaft. The device is applied and tightened in thesame way and a few turns of the handle will serve to loosen the wheel.

It will, of course, be understood that this device is applicable to anymake and variation ofautomobile wheel, and if sufliciently heavily madecan be used to remove heavy wheels from shafts such as are used, for

exam le in machine sho s.

I claim:

1. A wheel remover comprising a rotatable screw threaded shaft, and ahandle se cured thereto, a member adapted to be moved along said shaftby thejrotation of said 'shaft, means, adapted to prevent its rotationwith the shaft, for securing it to automobile wheel, the end of saidshaft opposite the handle terminating in a cylindrical section of lesserdiameter than the screw threaded portion of the shaft, an aperturedbearing plate, in rotatable relation said shaft, means, adapted toprevent its rotation with the shaft, for securing it to an automobilewheel, the end of said shaft opposite the handleterminating in a cylindrical section of lesser. diameter than the serew threaded portion ofthe shaft, it terminating in a cdnicaltip, vand anapertu-red bearing"plate in rotatable relation with -the shaft, and reniovably mountedupon said cylindrical section and adapted to. abut against the shoulderformed the intersection of'the reduced portion and the screw threadedportion of the. shaft.
